The films have sheet resistances as low as similar to 125 Omega square(-1) with 97.4% optical transmittance, and exhibit the half-integer quantum Hall effect, indicating their high quality. We further use layer-by-layer stacking to fabricate a doped four-layer film and measure its sheet resistance at values as low as similar to 30 Omega square(-1) at similar to 90% transparency, which is superior to commercial transparent electrodes such as indium tin oxides.
